The Warburg hypothesis ( / ˈvɑːrbʊərɡ / ), sometimes known as the Warburg theory of cancer, postulates that the driver of tumorigenesis is an insufficient cellular respiration caused by insult to mitochondria. [ 1] The term Warburg effect in oncology describes the observation that cancer cells, and many cells grown in vitro, exhibit ...
Mutagen. The international pictogram for chemicals that are sensitising, mutagenic, carcinogenic or toxic to reproduction. In genetics, a mutagen is a physical or chemical agent that permanently changes genetic material, usually DNA, in an organism and thus increases the frequency of mutations above the natural background level.
Linitis plastica (sometimes referred to as leather bottle stomach) is a morphological variant of diffuse stomach cancer in which the stomach wall becomes thick and rigid. [ 1] Linitis plastica is a type of adenocarcinoma and accounts for 3–19% of gastric adenocarcinomas. [ 1] Causes of cancerous linitis plastica are commonly primary gastric ...
Bottled water contains millions of small particles, thousands of which are nanoplastics so tiny they can invade the body’s cells, a study finds. Bottled water packed with nanoplastics, study ...
Carcinogenesis, also called oncogenesis or tumorigenesis, is the formation of a cancer, whereby normal cells are transformed into cancer cells. The process is characterized by changes at the cellular, genetic, and epigenetic levels and abnormal cell division. Cell division is a physiological process that occurs in almost all tissues and under a ...
A 2018 study found that tap water has fewer microplastics than bottled water, making it a likely better bet. Filtering your water is another possible way to decrease microplastics in drinking ...
Americans drink more bottled water than coffee, tea, milk, soft drinks or any other beverage — billions of gallons a year in all, according to industry statistics. That impressive thirst has ...
Genotoxicity is the property of chemical agents that damage the genetic information within a cell causing mutations, which may lead to cancer. While genotoxicity is often confused with mutagenicity, all mutagens are genotoxic, but some genotoxic substances are not mutagenic. The alteration can have direct or indirect effects on the DNA: the ...
